SHEET-METAL HUB.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Renewed September 21, 1008. Serial No. 454,002.

T 0 all whom it may concern:

Be it known that I, Crmnnns l'lniuz'r, a citizen of the United States, residing at Alexandria, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Sheet-Metal Ilubs, of which the following is a specification.

The present invention relates to vehicle wheels and especially to the'hubs thereof, and has for its object the provision of a hub which will be cheap in first cost, light, but strong, composed of comparatively few parts and one which may be easily assembled, or dismembered, if desired.

Most of the parts of the hub are preferably made of sheet metal, so as to be light and durable and yet combine great strength.

The invention consists :in certain novel features of construction and combinations and arrangements of parts as will be specified, and more clearly pointed out in the claims, reference being had to the accompanying drawings, in which one example of the physical embodiment of my invention is illustrated.

Figure 1 is an elevation of a wheel including my improved hub. Fig. 2 is a side elevation of the wheel hub, showing the fragments of two spokes. Fig. 3 is a longitudinal vertical central sectional view of the hub. Fig. 4: is a similar view of parts forming the hub, detached. Fig. 5 is a central transverse sectional view of the hub.

Referring to the drawings, the numeral 1 designates the hub as a Whole. The spokes 2, felly 8, and rim t, may be of any approved construction, but are preferably as shown in my two applications for patent on the spoke and felly, numbered 802,07 2 and 302,070 respectively, and filed as of even date herewith.

The hub consists essentially of the two conical shells 5 and 6, and their inclosed parts. These shells are formed, respectively, with annular flanges 5 and 6 and are held together by the bolts 7, which are passed through complementary holes 8, and be tween these bolts the spokes 2 are locked or held, as by the curved recesses 9 in the spokes. hub, I preferably locate a strengthening ring 10, which is brazed to the inner surface of the cylindrical end of the shell 5.

The interior of the hub is made of several At the outer or smaller end of the interlmtking members. I provide two frusto conical shells ll and 12, and these shells are complemenlary to and adapted to lit neatly within the outer shells or casings 5 and (3 respectively. At their smaller ends each of said shells l1 and 12 is provided with a ring or band ll and l2 and these rings or hands are brazed to the flanges .13 and l t 0f the inner shells. At their inner sides the bands or rings ll and l2 are formed with teeth 1.5 and to for a purpose to be described. The inner open ends of the interior shells it and 12 are closed by means of the flanges l7 and 18 of the cylindrical sleeves l0 and 20 respectively.

The flange 17 is provided with an offset 21. at its extreme edge and over this offset the lip 22 of the shell 11 projects to hold the shell ll in place. lVithin the shell ll and also incased by theslceve 19 is the tiller block 22, preferably of wood. At one end of the block is secured by screws 2 passed through the flange 17 and into the wood, and at its other end is engaged by the teeth 15 of the band 11 to hold it securely in place. This filler block 22 is provided with an elongated sleeve 24, which, as before stated is incased by the sleeve 19. The metallic sheave 19 is surrounded by the metallic sleeve 20, and the flange 18 of said sleeve 20 is offset at 25 similarly to the flange 17 and said offset is engaged by the lip 26 of the inner shell 12. A second filler block, of wood, as 27 is incased within the shell 12 and held therein by screws 28 and teeth i l, similarly to the block 22.

After the assembling of the before mentioned parts, the usual tapering aXleboX 29 is forced into the opening formed by the wood filler blocks, this opening of course being bored out true and tapered to receive the axle box.

In actual practice my present invention has overcome many objections and difficulties found to be present in wheel hubs constructed as on the general principles herein set forth.

By the use of the present invention in which the parts are mainly constructed of stamped sheet metal, I have found it desirable to braze the toothed rings 11 and 12 to the flanges 13 and 1 of the inner shells.

The strengthening ring 10 is also brazed to the shell 5.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a hub, the combination with the axle box, of a plurality of filler pieces surrounding the same, a pair of outer hub shells haV- ing flanges united by bolts, a strengthening ring brazed to the inner surface of the outer shell at the small end of the hub, and a pair of inner shells interposed between the filler pieces and the outer shells, one of said inner shells bearing against said brazed strengthening ring.

2. In a hub, the combination with the axle box, of a plurality of wood filler pieces, an axle box incased by said pieces, a pair of outer hub shells having flanges united by at flange formed integrally at the outer endsof each of said inner shells, a toothed ring brazed to each of said flanges and the teeth thereof engaging the filler pieces, and means for securing the filler pieces at their inner ends.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES HEART.
